Understand, represent and modify lighting in images

Abstract: Lighting has a strong influence on visual appearance, yet understanding and representing lighting in images remains notoriously difficult. This talk explores recent works on object compositing, lighting estimation, and lighting representation. In particular,it highlights how diffusion models can be leveraged to enable precise light editing in images. Short bio: I am a PhD candidate … Read more

Material selection in 2D and beyond – methods, tricks and applications

Abstract: In this talk, we’ll explore image understanding from a material-centric perspective, namely through the lens of material appearance. Materials distinguish themselves by their response to light, which is governed and modelled through physical properties like roughness or gloss – however, understanding such properties is a non-trivial task for current models and network architectures. We’ll … Read more

Drawing Out: Artistic research into machine vision, material traces, and everyday devices

Abstract: The seminar will introduce my artistic practice and research, which explores how ubiquitous technologies can be used to reveal their own material, sensory, and image-making capacities. Through works made with scanners, robotic vacuums, window-cleaning robots, computer mice, printers, smartphone sensors, and thermal paper, I investigate how devices record, respond to, and interact with the … Read more

Experimental Analysis and Complexity Scaling of Denoising Diffusion Probabilistic Models for Image Synthesis 

Abstract: This talk will present an experimental study on the behaviour, scalability, and generative quality of Denoising Diffusion Probabilistic Models (DDPMs) for image synthesis across datasets of increasing complexity.   Three case studies are analysed and compared based on FID (Fréchet Inception Distance) evaluation metric and the performance of downstream classifiers to discriminate the synthetically generated … Read more

Tensor network methods for machine learning: tensorization, privacy, and beyond

Abstract: Neural networks (NNs) excel across a wide range of machine learning tasks due to their flexibility and scalability, but they also pose challenges in privacy, interpretability, robustness, and efficiency—limitations that can be especially critical for large models trained on sensitive data. To tackle these issues, we propose the use of tensor network models. In … Read more

A General Framework for Text Line Detection and Recognition

Abstract: I will start by introducing DTLR, our general approach for recognizing text lines, whether printed (OCR) or handwritten (HTR), using Latin, Chinese, or ciphered characters. Most HTR methods have focused on autoregressive decoding, which predicts characters one at a time. In contrast, DTLR processes the entire line at once. Our method shows strong results … Read more

Marrying Multi-view Geometry with Deep Priors for Image-based 3D Reconstruction

Abstract: We live in a world where all interactions with the environment necessitate a 3D understanding of our surroundings. While humans excel at reasoning about 3D structures from both multi-view and single-view images, replicating this capability in computers remains challenging due to the need to combine mathematically proven geometric knowledge with end-to-end learned priors. In … Read more
